Which head compression

[pinkpantherusmincus]

[h=2]I have a spare boon docker nos kit I am going to install though I would like some feedback on which head to use with it?[/h]

Its for a 04 summit 800ho, I have a stock head and a rk tek head running 13:1. Which one should I use?

I am worried about too much pressure and per ignition in the cylinder using both nos and high compression head?

Thanks

You think with the extra compression it will pre ignite?

As maxwell said. If you use the 13:1 run a minimum of 50/50 even when not using nos. cheap insurance.
